A growing attention has been paid to spatial data mining and knowledge discovery (SDMKD). This paper presents the principles of SDMKD, proposes three new techniques, and gives their applicability and examples. First, the motivation of SDMKD is briefed. Second, the intension and extension of SDMKD concept are presented. Third, three new techniques are(More)
TSR (Traffic sign recognition) has been studied for realizing drivers assisting system and automated navigation and is an important studied field in ITS (Intelligent traffic system). In this paper, a recognition method of traffic signs separated from real image was studied. Images were divided into several categories according to the actual weather,(More)
TSR (Traffic sign recognition) is an important problem in ITS (intelligent traffic system), which is being paid more and more attention for realizing drivers assisting system and unmanned vehicle etc. TSR consists of two steps: detection and recognition, and this paper describe a new traffic sign detection method. The design principle of the traffic sign is(More)
Data mining techniques are studied to discover knowledge from GIS database and remote sensing image data in order to improve land use classification. Two learning granularities are proposed for inductive learning from spatial data, one is spatial object granularity, the other is pixel granularity. The characteristics and application scope of the two(More)
A new sub-pixel block matching algorithm for fast motion estimation is proposed, which is designed to reduce the search position by using the distortion information of the evaluated integer points in the small diamond search pattern. In order to use the single instruction multiple data (SIMD) technique to fast parallel implement it, the storage order of the(More)

One of the main obstacles in image registration is the precise estimation of a mapping function that determines geometric transformation between two image coordinate systems. For conventional image registration methods, their registration results are not the global optimal, and accuracy is low because only a few local control points are used for the(More)
In this paper, the trend of urban spatial information sharing service from the electronic map to image is analyzed and its sharing framework based on service-oriented architecture is designed. Moreover, the service implementation, feedback data service procedure and its processing service model are explored. Based on the software with independent(More)
